Noise Nuisance Recorder User Manual Guide
Making a recording
Audio recordings are controlled by the Wireless
RC:199 Remote Control.
Starting a recording
To start an audio recording, press the Record
button on the Remote Control.
The red Indicator Light on the Remote Control
will show when the key is pressed.
Recording Indicator on the lid of the case will
flash blue and then turn red.
This can be seen on the top of the case and is
labelled as the Record indicator.
When an audio recording is active, the graph on
the instrument display will be coloured blue.
The noise level bar at the left hand side of the
display will also be shown in blue and the Audio
key will be highlighted.
The maximum length of a single audio recording
is 5 minutes. This ensures that if the user forgets
to stop the recording using the remote control,
the memory of the instrument is not filled with
excessive and possibly unwanted recordings.
If the recording reaches the 5 minute limit, the instrument will automatically stop the
audio recording and store the information. The measurement of noise levels will
continue as normal.
Stopping a recording
To stop an audio recording, press the Stop button on the Remote Control.
The Record indicator will flash blue and then go out. The audio recording has now
stopped. The sound level meter will continue to measure and store the noise levels.
Pre-Trigger & Post-Trigger
The Trojan
LITE
provides a Pre-Trigger and Post-Trigger function for the audio recordings.
As standard, these are both set to 20 seconds.
When a recording is activated, the instrument will store the previous 20 seconds of
audio from before the button was pressed and when a recording is stopped, the
instrument will continue to store audio for a further 20 seconds.
When the Post-trigger is active, the Record indicator will not be lit but the audio will still
be recorded.
